GATEl SPECIFICATION forming part of Letters Patent No. 758,559, dated April 2 6, 1904.

i Application led .Tune 6, 1903. Serial No. 160,376. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, PA'UL OPPENHEIM, acitizen of the United States, residing at 65 West Forty-fifth street, in the city, county, and State of New York, have invented a certain new and useful Improvement in Gates, of which the following is a full, clear, and eXact specification.

My invention relates to improvements in gates, and the object of the invention is to provide an extremely simple form of gate which will open'- in a minimum amount of space, which shall move easily in opening and closing, and which may be readily operated from a distance. A gate of this character is particularly adapted for use in railway-cars and similar vehicles. When the platforms of such vehicles are crowded, as frequently occurs in the street cars of cities, it is eX- tremely difficult for the brakeman or guard to open or close the gate. Moreover, when gates as now constructed are opened and closed much inconvenience is caused the passengers by the inward and outward turning of the gate on its hinges. In my construction this difliculty is obviated, the gate, as I have invented it, being capable of operation by the brakeman at a distance and also being slidably mounted upon its bearings. The latter feature avoids the inconvenience and danger to passengers always present when a gate which opens inwardly or outwardly is employed.

To this end the invention comprises the details of construction and arrangement of parts whereby the desired results are secured in the manner hereinafter described.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view; Fig. 2, a front elevation; Fig. 3, a side elevation.

In the drawings similar parts are designated by similar reference-numerals.

The numeral ldesignates a fence alongthe side of a roadway leading to a point where a gate is located or portion of the guard-rail of a surface or elevated car.

The gate comprises a main section 2 and a supplemental telescoping section 3, slidingly supported by the main section. The main section is formed of upper and lower channelbars 4, which are arranged with the channels facing each other, and these are united at one side by a vertical bar 5, which is preferably also channeled. The walls of the bars t on one side are connected by vertical bars 6, as shown. This main gate-section is slidingly mounted upon a track 7, having a guideway 8 therein, which is engaged by a projection or guide 9 on the under side of the gate-section. At the top the gate-section is guided in a suitable guideway 10. The supplemental gate-section 3 has upper and lower bars 11, which for convenience I make of channel-iron similar to the channel-bars of the main gatesection, but of a size adapted to slide within the channels of the main bars. At the front end the upper and lower bars are connected by a vertical bar 12, and additional vertical bars 13 connect the upper and lower bars, as shown. The lower bar is provided on one side with a cut-away portion, leaving shoulders 11a, which are adapted to engage in the movement of the supplemental section with a stop 13X on the main gate-section, and thus limit the movement of the supplemental section in relation to the main section. The outer or front end of the supplementalsection is guided by a projection or guide entering the groove or guideway of the supporting-track. In order to operate the gate, a crank-shaft 14 is mounted in a stationary bearing 15, and this crank-shaft has a crank 16, the free end of which is connected by a link 17 to a lug on the front vertical bar of the supplemental gate-section. It is obvious that the crankshaft could be extendedto a suitable distance from the gate, so that the latter could be operated from a reasonable distance; but as this is not always convenient I also provide a rockshaft 18, which is inclined at an angle to the crank-shaft and connected thereto by a universal joint 19. At its remote end the rockshaft is provided with a bevel-gear 20, which meshes with a similar gear 21, mounted upon a stationary aXis and provided with a suitable operating-handle 22. The bevel-gear 21 is preferably of larger diameter, so as to securev a multiplying action.

It will be obvious that while I have shown IOO and described a side fence or rail guard approaching the gate this is merely forthe convenience of illustration, but is not necessary, as the invention might be used equally well where the only fence or guard was one intersecting the other at right angles thereto, in which event the parts would be supported by suitable posts. It will also be obvious that my invention contemplates the use of a rockshaft and operating-handle on both sides of the gate; but for convenience of illustration I have shown it on one side only.

Having thus described my invention, what I claim is- 1. Ina sliding gate, a main gate slidingly supported and comprising upper and lower channeled bars with vertical bars connecting the same, a supplemental gate having upper `and lower horizontal bars sliding in the channels of said channeled bars, means for limiting the movement of the supplemental gate in relation to the main gate, and operating means connected with said supplemental gate substantially as described.

Q. In a sliding gate, a main gate comprising upper and lower channeled bars, a vertical channeled bar connecting said bars at one end, vertical bars connecting the flanges of the upper and lower bars at one side of the gate, a supplemental gate having top and bottom bars sliding in the channels, a stop for limiting the movement of the supplemental gate in relation to the main gate, a crank-arm carried by a shaft mounted in stationary bearings, and a link connecting the crank-arm with the front end of the supplemental gate, substantially as described.

3. In combination, a track having a groove or guideway, a main gate-section comprising upper and lower channeled bars suitably connected and having the channels facing each other, a guide from the lower bar engaging said guideway, a supplemental gate-section sliding in said channels, a guide on the outer end of said supplemental section engaging said guideway, means for limiting the movement of the supplemental gate in relation to the main gate, and operating means connected with the supplemental gate-section, substantially as described.

4. In combination, a main gate-section slidingly supported, a'supplemental gate-section sliding] y connected with the main gate-section, a crank-shaft journaled in a stationary bearing, a link connecting the crank with the supplemental gate-section, a rock-shaft connected to said crank-shaftby a universal joint and extending to a distance from and at an angle to said crank-shaft, a bevel-gear on the distant end of said shaft and a hand-operated bevel-gear meshing with the gear on the shaft, substantially as described.

In witness whereof 1 have hereunto set my hand in presence of two witnesses.
